New complementary logic circuits using coupled quantum wells
Abstract
We present new complementary logic circuits that exploit an intrinsic bistability in nano-scale coupled quantum wells. When operated with a multiple-phase split-level clocking scheme, the device can latch a binary digit while meeting gain, tolerance, and I/O decoupling requirements at the same time, which were difficult with conventional back-to-back negative differential resistance devices. This same structure can function as a complete set of classical complementary logic circuits as well, by changing only the connections of the input signals. When these circuits are cascaded, efficient charge recycling can be achieved. ©2004 ieee.
